VecScale
Scales a vector.
Synopsis
#include "petscvec.h"
PetscErrorCode VecScale(Vec x, PetscScalar alpha)
Not collective on Vec
Input Parameters
| x | - the vector
|
| alpha | - the scalar

Output Parameter
Note
For a vector with n components, VecScale() computes
x[i] = alpha * x[i], for i=1,...,n.
Level
